Hesitation

Hey guys, i got a little problem here. Sometimes when i get on the gas in my truck, the motor hesitates for a couple seconds. It like sputters almost. I've noticed it that past coupld times that i've gotten on the gas hard. I have put a cold air intake on it, do you think that it could be running a little lean? Especially up here in New Hampshire with the air so cold this time of year? I've put a can of fuel injector cleaner in the tank, and that seems to work a little, although not very noticable.

anything and everyting is greatly appreciated

Thanks guys,
Garrett

I would check all the connections and make sure its not a leak in the intake tube or a loose vacum line.

I also experience the same problem with my 4.2V6. Can this be caused by faulty spark plug wires?

Usually bad plug wires will give you a misfire which feels like a buck or jerk. When I think of a hesitation I think of pressing the gas pedal and it doesn't respond. It takes some time, hesitates, before it goes.

I encounter some problems running between 55 - 60 mph. I feel that my engine suddenly sputter and when I press the gas pedal, it disappears. I just changed my fuel filter last September.
